Caution:
1.As this pet fountain pump is submersible, you need to put it into the water completely before powering it on to avoid the aquarium pump burning out. Prohibit running with no load. Prolonged running in the air will shorten the life of this machine and make a lot of noise, please disconnect the power supply when changing water.
2.Insufficient power and frequency will affect the flow rate of the fountain pump.50GPH is the flow rate without using the water pipe of the pump. If connected to the pump water pipe, the maximum flow rate of the fountain pump will be less than 50GPH.
